Fixed inductors refer to a kind of special electronic components, which are also called arrow coils or mains chokes. SP1812-124K is a fixed inductor with the following features: rated current of 24A, rated voltage of 420VAC, inductance of 12.4mH. It has a wide application in the fields of communication, power supply, industrial control, and motor control.

The working principle of SP1812-124K fixed inductor is based on its structure. Using the physical principles of electromagnetic fields, the inductance of an inductor can be increased by correctly winding the wire of the inductor into a coil. The amount of windings determines the inductance value. The larger the number of windings, the higher the inductance value. The inductor\'s inductance determines its reaction to the frequency of the alternating current (AC). The higher the frequency of the AC, the smaller the induction value, and the resistance to current flow increases.

The SP1812-124K fixed inductor is widely used in the acoustic field because its inductance change is small and stable and it has good filtering performance. It also has advantages in power frequency and harmonic suppressor, where it can filter interference signals effectively and reduce pulsation in the output signal. Therefore, it is used for power supply to electric equipment, LED lamps, and incandescent lamps.

In motor control applications, the SP1812-124K fixed inductor can withstand operating frequency up to 50kHz. It is used to filter, buffer, and provide over-current protection, as well as to reduce pulsation in motor current. This helps reduce torque glitch and improves motor rotation accuracy.

In industrial control applications, SP1812-124K fixed inductor resistance is low at low frequencies. It provides better protection against voltage spikes and surges, and also helps reduce electromagnetic interference (EMI). This reduces signal distortion and improves the reliability of the entire system.

The SP1812-124K fixed inductor is a versatile electronic component that can be used in a wide range of applications. It is an ideal choice for power supply and motor control, as well as providing reliable protection against voltage spikes and surges. Its low temperature coefficient allows it to perform well even in harsh environmental conditions.
